## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability clearcheck-weather-us-point-forecast-with-nws-alert-verdict-4ced0f3d
```

Example prompt: What's the weather forecast and are there any active NWS alerts at latitude 39.7456 and longitude -97.0892? Give me the next 4 forecast periods and tell me if conditions are CLEAR, ADVISORY, or WARNING.

## When to prefer this

Choose this endpoint when you need both an NWS point forecast AND an aggregated safety verdict (CLEAR/ADVISORY/WARNING) in a single call for a US location specified by coordinates. It is preferable over raw NWS API calls because it bundles alert checking and verdict classification, saving multiple round-trips. Best suited for go/no-go decisions, safety screening, or situational awareness workflows where a simple verdict label is needed alongside forecast details.

## Known failure modes

- Coordinates outside the contiguous US (NWS does not cover all territories) — returns an error or empty forecast
- Invalid or out-of-range lat/lon values — schema validation error
- NWS API temporarily unavailable — upstream timeout or 503
- Network error connecting to render-hosted service — 502 or connection timeout
- Missing required lat or lon query parameters — 400 bad request

## How this service works
